What is the SMSB242/SMSB482?
Elbro AG developed the SMSB242/SMSB482 to meet the widest range of customer requirements. It is an innovative tool for the
remote control of private and industrial applications via the GSM network. This new system enables remote activation of up to
four devices (up to two for SMSB242) and the monitoring of up to eight alarms (up to four for SMSB242) by means of simple
SMS commands. The SMSB482 has four 5A relay outputs and eight zero-potential alarm inputs which you notify the stored ad-
ministrators via SMS about the status of the installation, such as faults within an installation. The SMS text is freely configurable
for each alarm input for both normally open and normally closed contacts. The device is password-protected and can store and
manage up to eight users.
In order to simplify installation and operation of the device, the SMSB242/SMSB482 is equipped with a large, intuitive LCD dis-
play, which shows information about the GSM signal strength, status of the inputs and outputs, date and time, any errors, etc.
The SMSB242/SMSB482 is very versatile: With the two built-in PT100 and PT1000 analogue inputs which are freely configura-
ble to 0-10V, 0-20mA with code switches, it is possible to set up to two thresholds per analogue input, which trigger an SMS
alarm when the values are undercut or exceeded. The measured values are shown directly on the display and via SMS by
means of a status query. They can also be recorded electronically in the integrated Micro SD card (datalogger function).
The SMSB242/SMSB482 operates with subscription or prepaid mini SIM cards from mobile telephone operators, the DIN hous-
ing enables easy installation into the switch cabinet, the operating voltage is 12-24VDC, the configuration can be transmitted via
PC software and mini USB connection. The installation software is saved on the integrated Micro SD card and is thus safe-
guarded against loss and can be used after several years for reprogramming.
Thanks to the built-in backup super capacitors, the stored users can notified of any potential power failures via SMS.
